Four new coumarin derivatives from Artemisia keiskeana

J Nat Prod. 2001 Aug;64(8):1081-3. doi: 10.1021/np010103a.

Abstract

Four new coumarin monoterpene ethers, artekeiskeanols A-D (1-4), and three known coumarins, isofraxidin, fraxidin, and daphnoretin, were isolated from the whole plants of Artemisia keiskeana. All structures were determined from spectral data, and that of artekeiskeanol A (1) was confirmed by synthesis.
